Lower atmosphere water/hydrogen activity during the MY 34 regional dust storm [PDF]

open access: gold, 2020
Our understanding of the evolution of water on Mars can be advanced through the provision of bounded constraints on the rates of water loss. To understand observed variations in the loss rate, the processes via which hydrogen escapes the martian atmosphere and coupling to the lower atmosphere water cycle also need to be explored.

Severe dust storm/thunderstorm activity over Uttar Pradesh on 13th May, 2018 - A case study

open access: diamondMAUSAM, 2023
Premonsoon season over Uttar Pradesh is characterized withthunderstorm  accompanied with rain, dust storm, gale winds and hail storms etc. These storms generally develop locally in association with convection and moisture convergence and seen as single cells in Doppler Weather Radar, but sometime these thunderstorms are associated with synoptic scale ...

Relationship between frontal dust storms and transient eddy activity in the northern hemisphere of Mars as observed by Mars Global Surveyor [PDF]

open access: yesJournal of Geophysical Research: Planets, 2005
We have compiled a catalog of frontal dust storms in the northern hemisphere using Mars Orbiter Camera daily global maps spanning ~2.3 Martian years of Mars Global Surveyor (MGS) observations (from 1999 to 2003).

On the importance of Mongolian cyclones to East Asian dust storm activities

open access: gold
Desert-dust aerosols affect the climate, human health, and socio-ecomomic activities. In East Asia, the passage of Mongolian cyclones induce dust-emitting winds in the Gobi Desert. While cyclones are known as driver of dust outbreaks, the relative contribution of Mongolian cyclones to the total East Asian dust emission amount and the dust aerosol ...

Detecting electrical activity from Martian dust storms [PDF]

open access: yesJournal of Geophysical Research: Planets, 1999
We present a model addressing the possible electrification of Martian dust storms based on the effective electrical charging of an individual dust grain. An upper charge bound on a grain can be determined based on the grain capacitance in the low‐pressure Martian atmosphere.

Dust, Sand, and Winds Within an Active Martian Storm in Jezero Crater

open access: yesGeophysical Research Letters, 2022
AbstractRovers and landers on Mars have experienced local, regional, and planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive. Over 5–11 January 2022 (LS 153°–156°), a dust storm passed over the Perseverance rover site.

The Spatial and Temporal Probability of Dust Storm Activity in Chryse, One of the Tentative Landing Areas of Tianwen-1 Mission [PDF]

open access: greenUniverse, 2020
Dust storms, observed in all seasons, are among the most momentous of Mars’ atmospheric activities. The Entry–Descent–Landing (EDL) activity of a Martian landing mission is influenced by local atmospheric conditions, especially the probability of dust storm activity. Chryse Planitia, featuring many of the largest and most prominent outflow channels and

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

open access: yesGeodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Vegetation Cover Variation and Dust Frequency Analysis Over West of Asia [PDF]

open access: yesNīvār, 2023
Dust is one of the major environmental problems that make health and financial losses in arid and semi-arid regions. As a country located in the Middle East, Iran has been affected by these natural hazards and every year dust storms occur in different ...
